Welcome to the Miata world! We have similar builds but mine is a 93 with a 1.8 swap out of a 96.
As for Super vs turbo that is your decision, but I vote turbo. Join the TurboMiata forums and start looking around. A lot of cool things going on like viewing peoples progress on their turbo builds. Who knows, you may even find a build that you want to copy.
Again, welcome!
